Receive an answer

The app needs to receive an answer (a session description in SDP format) from the call recipient (the person receiving the call). The app expects this answer to be stored inside a structured data with an ID based on the random ID provided by the caller.

If the structured data doesn't exist, the app waits 2 seconds and tries again. The app keeps making GET requests to the SAFE Network until it finds a structured data with an ID based on the random ID provided by the caller.
